If you want tips check out the mig welding forum. Lots of gas bottle stoves on there.

We inherited a load of old 47kg cyclinders when we bought the farm- they make fantastic pig troughs!

1mm cutting disks are good as well.

The valve needs a good stiltson wrench & about a 6 foot bar to undo it (and a way of holding the cylinder still).

We tried everything (including cursing) to get the valve off.
I'm not a wimp but not quite strong enough to hold it steady whilst vp was bashing the bar!

I suspect when being serviced they use a heavy duty clamp which engages in the rim of the cylinder locking it tightly and the valve is replaced rather than refitted. It might even be more cost effective simply to throw them away judging by the state some of them are in.

I saw one of these made into a little stove for a caravan. The valve was taken off and a flue fitted onto it and a hole cut out of the side at the bottom. It worked a treat except that the actual bottle got really hot. Acted like a radiator but needed a guard around it all the time. Perhaps good for an outdoor one though

I have 2 of the 19kg ones that I can't get rid of that I ought to do something with if I can get around to it. All I have is an angle grinder though.

A simple cure for that problem is to encase a smaller cylinder inside a large one with minimal contact between the two. That way the surface temperature is lower and the resulting hot air can be more effectively channelled. It makes the stove heavier though.

A risk issue with home made indoor stoves is that you have to paying very careful attention to design and build quality to avoid the risk of carbon monoxide poisoning or fumes. From an hobbyist point of view I'd avoid building stoves for internal use but reserve their use for well ventilated areas.

I'm using the smaller of the two gas cylinders to make the stove. I cut off the base and the carry handle and then cut a hole which will server as the fire door in the base of the tank.

The door will be made from the cut out blank. I'm going to weld a flange around the perimeter to provide a nice finish (the Oz Pig doesn't have this) but I need to get my forge made first so I can fabricate the flange. The door will be fixed with an offset hinge and I'll forge the handle and latch and probably rivet it on rather than weld to add to its overall aesthetic. My cutting skills need improving.

I hit on the idea of using the base to make the feet.

and hopefully when welded it will start to look like...

It's got its rump in the air as the rear legs were cut a little higher than the front. I've since fettled them to the same overall height so the stove will sit level.

Next steps are to cut out the top hole and fabricate a collar to act as a hotplate stand and then make the flue outlet and flue.

Looking at the Oz Pig site for reference this beasty is going to be about twice as big.

Somebody I met was talking about using welding gas bottles as tube header drums in a water tube boiler for his steam launch

Too many projects. Too busy working. It's in exactly the same state as the last photo.
